To all whom it may concern.

Be it known that I, JAMEs E. ALLoNBY, a citizen of the United States,and resident of Stamford, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inEmergency Devices for Automobile-Springs, of which the following is aspecification.

My invention relates to the construction of temporary repairs forlaminated vehicle springs.

The object of the invention is to provide a simple and inexpensivedevice adapted for ready application to a laminated vehicle spring incases where a break occurs in one or more of the laminations, for thepurpose of providing a temporary repair.

The invention is especially useful for repairing springs of automobiles.

The invention consists, briefly stated, of a plate or truss adapted forapplication to the spring in a manner to span the break longitudinallyand provided at its opposite ends with depending ears or lugs adapted toembrace the edges of the spring, one of the ears at each end beingprovided with a clamping set screw tapped into the ear and adapted toengage one edge of the spring while the ear on the other side engagesthe opposite edge and is adapted to hold the broken or fractured leavesagainst longitudinal displacement.

The invention further consists of the construction of device and of itsdetails as hereinafter more particularly described and then specified inthe claims.

Figure 1 of the accompanying drawings is a plan of a device embodying myinvention.

Fig. 2 shows the same in edge view at one end and in longitudinalcentral section at the other end.

Fig. 3 is an end view of the device.

1 indicates the body of the device consisting of a plate or other shapeof steel or other good material and formed preferably in a truss shapeas indicated in side view. At each of its opposite ends the body 1 isprovided with depending lugs or ears 2, 2. The plate or body is adaptedfor application to the top of a broken or fractured laminated spring ina manner to bridge the broken or fractured spot while the lugs 2, 2 areadapted to engage the edges of the spring and to embrace the springbetween them. The lugs 2 at one side are each provided with set screws 3operable to clamp the device to the spring in cobper'ati'oi'iwith thelugs or flanges 2 at the opposite side or edge of the spring in obviousmariner. Preferably the lugs '2" are formed on their engaging surface insuch manner as to positively prevent the shifting of the broken plate ofthe spring longitudinally by biting into the edge thereof and for thispurpose each may be provided with serrations extending transverselyacross the edge of the spring as indicated in the side view Fig. 2.

In place of scorings or serrations such as shown, the surface mightobviously be formed in other ways to positively hold the two halves ofthe broken plate against longitudinal displacement with relation to thesound or unfractured plates from which the spring is built up.

As will be seen, my device can be readily used with springs of differentwidth by making the stem of the set screw 3 of sufficient length. In usethe set screws are turned back sufliciently to permit the plate or truss1 I to be applied to the top of the spring with the center portion ofthe truss or plate over the point of fracture and with the lugs,eXtending down transversely to the spring along its edges. The set screws 8are then turned up thus binding the spring between the lugs and causingthe serrations or scorings or other irregular formation onthe enga ingface of the lugs 2 to bite all the leaves of the spring including thefractured leaf. This completes the repair. Ordinarily the use of thescrews 3 will be sufiicient to firmly fasten the repair and preventdisengagement thereof during'travel of the vehicle but, if de sired,additional means may be employed for holding the repair againstdetachment, such for instance as the yoke 4: applied to the top of therepair and fastened in place by the nuts 5.

What I claimas my invention is:

1. A repair for laminated vehicle springs comprising a body adapted tospan a break longitudinally of the spring and provided with two pairs ofdepending lugs or ears, one pair at each end, one of the ears of eachpair being provided with a set screw adapted to engage one edge of thespring while the opposite ear of said pair has an engaging surfacebearing against the opposite edge.

2. A repair for laminated vehicle springs consisting of a plate havingat each end a pair of depending lu s and adapted to embrace the edges ofthe spring, one of said 10 vided With a clamping set screw and the otherbeing provided With serrations upon its engaging face and extendingtransversely of the leaves of the spring.
